First thing to do for any beginners in computer programming is to choose a language, and if possible the most easier for you!

Starting directly with C is not the most good choice. Especially if you try with an OS dedicated SDK!
If you're really sure to use the C, try to perfectly understand and use the C-ANSI before any OS sdk.
Or use more high level languages likes some Basic(s), Arexx, Python, ...

After, if C-ANSI is boring for you, try an OS sdk and code for this one simple applications (likes ones in C-ANSI but using OS API), then play with more complicated stuffs like graphics, GUI, sounds, etc.

Don't forget also that some high level languages are easier to use when high level suffs like GUI-programming are requiered.
